Wherein the second preset angle alpha 2 May be determined according to the distance between the user and the air conditioner, for example, at a second preset angle alpha 2 The upper boundary line of the flow field of the downward air outlet of the air conditioner is at a distance 1 from the air conditionerThe height of the rice position is less than 0.5 meter, so that the problem of directly blowing hot air to the face is avoided, and the use requirements of most users can be met; or, a second predetermined angle α 2 Can not have the gap according to the projection of first yaw leaf subassembly 4 on vertical plane and set for the benchmark, if there is not the gap in the projection of first yaw leaf subassembly 4 on vertical plane, then show that the air-out can not flow from the place ahead of air outlet, when the user looked at the air outlet from the dead ahead of air conditioner simultaneously, first yaw leaf subassembly 4 was similar to and seals the air outlet, therefore can obtain the look and feel of preventing directly blowing and experience.
In the control method of the air conditioner provided by the embodiment, the air conditioner is provided with the first horizontal swing blade assembly 4 in the lower half area of the air outlet 2, and the second horizontal swing blade assembly 5 and the vertical swing blade assembly 3 are sequentially arranged in the upper half area from inside to outside, compared with the existing air conditioner, the air conditioner is provided with the vertical swing blade assembly in the lower half area of the air outlet and the first horizontal swing blade assembly 4 is arranged outside, so that the flow field of the air outlet gas is improved, the lower boundary line of the flow field in the cooling mode moves upwards, the upper boundary line of the flow field in the heating mode moves downwards, the range of the air outlet direct blowing user is further reduced, and the effect of preventing the air conditioner from direct blowing is improved; simultaneously because first yaw leaf subassembly 4 is external, can also directly give the user in the vision in order to prevent the impression experience of directly blowing, improved user's use comfort.
Further, in the embodiment of the present invention, step S100 further includes:
step S110: and acquiring a set temperature value of the air conditioner and an indoor temperature value of the environment where the air conditioner is located. Specifically, the indoor temperature value of the environment where the air conditioner is located may directly adopt a first room temperature measurement value measured by a room temperature sensor inside the air conditioner; or the indoor temperature sensor which is positioned in the room and farthest away from the air conditioner can be connected with the signal to obtain a second indoor temperature measurement value, and the average value of the first indoor temperature measurement value and the second indoor temperature measurement value is used as the indoor temperature value.
Step S120: and calculating a temperature difference value between the set temperature value and the indoor temperature value, and determining whether the temperature difference value is greater than a preset temperature difference value. Specifically, the preset temperature difference may be preset according to actual conditions, for example, the preset temperature difference may be 3 ℃.
Step S130: if yes, sending out inquiry information whether to start the direct blowing prevention function to indoor personnel.
Specifically, if the indoor temperature value is greatly different from the set temperature value, the air outlet speed of the air conditioner is high, and indoor personnel may come to manually start the direct blowing prevention function through an operation panel, a remote controller or a mobile terminal of the air conditioner after being directly blown by the air outlet of the air conditioner, but the direct blowing of the air conditioner causes bad experience for users under the condition. In order to avoid the direct blowing of the user, when a large temperature difference is detected, inquiry information about whether the direct blowing prevention function is started or not can be sent to indoor personnel actively in time, and then avoidance is carried out in advance. Here, the inquiry information may be issued to the user through a voice controller, or the user may be prompted by flashing a text or sounding an alarm on a display panel of the air conditioner.
Step S140: and if the confirmation information of the indoor personnel or the feedback information of the indoor personnel is not received within the first preset time, triggering the direct-blowing prevention function to start.
Specifically, the manner of receiving the feedback information here may be that the voice controller receives voice determination information sent by the indoor person, such as "yes", "good", "agree", "ok", and the like, or may also be that the indoor person sends determination information through an operation panel of an air conditioner, a remote controller, or a mobile terminal. The first preset time is preset for the system and can be set to be 2-3 minutes, enough consideration time is provided for a user, and meanwhile the air outlet speed of the air conditioner is not improved, so that bad experience is not brought to the user. In addition, the first preset time may also be modified manually by the user through voice, a remote controller, a mobile terminal, or the like. And if the air conditioner does not receive the feedback information of the user after the first preset time is exceeded, starting the direct blowing prevention function by default.
Further, in the embodiment of the present invention, step S200 further includes:
step S210:when the air conditioner is in the cooling mode, as shown in fig. 3, if the second room temperature measurement value is greater than the first room temperature measurement value, the first traverse blade assembly 4 is controlled to swing upward to the maximum upward swing angle α umax And simultaneously controlling the air outlet direction of the second traverse oscillating blade component 5 to be parallel to the air outlet direction of the first traverse oscillating blade component 4, namely beta 1 ＝α 1 ＝α umax . At this moment, the temperature value detected by the temperature sensor in the house is greater than the temperature value detected by the temperature sensor of the air conditioner, the temperature of the space far away from the air conditioner in the house is not reduced, and in order to achieve the purpose of rapid refrigeration, the first transverse swinging blade component 4 and the second transverse swinging blade component 5 can be swung upwards to the maximum angle and send cold air to the far end of the house together.
If the second room temperature measurement value is less than or equal to the first room temperature measurement value, the first yaw blade assembly 4 is controlled to swing upwards to a first preset air outlet angle alpha 1 And the first preset air outlet angle alpha 1 ≤α umax And simultaneously controlling the air outlet direction of the second traverse oscillating blade component 5 to be intersected with the air outlet direction of the first traverse oscillating blade component 4, namely beta 1 ＜α 1 ≤α umax . At this moment, the temperature value that temperature sensor detected in the house and the temperature value that air conditioner temperature sensor detected differ a little, it is balanced to show the interior temperature field of house, need not to refrigerate fast this moment again, therefore can reduce the last pendulum angle of second yaw leaf subassembly 5 (or reduce the last pendulum angle of first yaw leaf subassembly 4 and second yaw leaf subassembly 5 simultaneously), make the air-out direction of second yaw leaf subassembly 5 and the air-out direction of first yaw leaf subassembly 4 crossing, thereby make the air-out of second yaw leaf subassembly 5 and the air-out of first yaw leaf subassembly 4 carry out airflow impact, form the unoriented natural wind of wind-force, prevent that strong air current from arousing user's discomfort. In one particular embodiment, the first yaw blade assembly 4 maintains a maximum pitch angle, α 1 ＝α umax The second horizontal swinging blade component 5 blows air in parallel, namely beta 1 ＝0。
Step S220: when the air conditioner is in the heating mode, as shown in fig. 4, if the second room temperature measurement value is smaller than the first room temperature measurement value, the first yaw blade assembly 4 is controlled to swing downward to the maximum yaw angleDegree alpha dmax And meanwhile, the air outlet direction of the second transverse swinging blade component 5 is controlled to be parallel to the air outlet direction of the first transverse swinging blade component 4, namely beta 2 ＝α 2 ＝α dmax . At this time, the temperature value detected by the temperature sensor in the house is smaller than the temperature value detected by the temperature sensor of the air conditioner, which indicates that the temperature of the space far away from the air conditioner in the house has not risen, and in order to achieve the purpose of rapid heating, the first and second traverse blade assemblies 4 and 5 can be swung downwards to the maximum angle, and hot air is delivered to the far end of the house together.
If the second room temperature measurement value is greater than or equal to the first room temperature measurement value, the first yaw blade assembly 4 is controlled to swing downwards to a second preset air outlet angle alpha 2 And the second preset air outlet angle alpha 2 ＜α dmax And simultaneously controlling the air outlet direction of the second traverse oscillating blade component 5 to be intersected with the air outlet direction of the first traverse oscillating blade component 4, wherein alpha is 2 ＜β 2 ≤α dmax . At this moment, the temperature value detected by the indoor temperature sensor and the temperature value detected by the air conditioner temperature sensor are not different greatly, which indicates that the indoor temperature field is balanced, and at this moment, the indoor temperature field is not required to be heated quickly, so that the downward swing angle of the first horizontal swing blade assembly 4 can be reduced (or the downward swing angles of the first horizontal swing blade assembly 4 and the second horizontal swing blade assembly 5 are reduced simultaneously), the air outlet direction of the second horizontal swing blade assembly 5 is crossed with the air outlet direction of the first horizontal swing blade assembly 4, and thus the air outlet of the second horizontal swing blade assembly 5 and the air outlet of the first horizontal swing blade assembly 4 are subjected to air flow impact, non-directional natural wind is formed, and discomfort of a user caused by strong air flow is prevented. In one particular embodiment, the second yaw blade assembly 5 maintains a maximum yaw angle, β 2 ＝α dmax The second preset air outlet angle alpha of the first horizontal swinging blade component 4 2 ＝α dmax Δ α, where Δ α is between 10 ° and 30 °, Δ α should not be too large, so as to prevent the air from blowing directly to the user from the first traverse blade assembly 4.
On the basis of the above embodiment, after step S100, the method further includes:
step S310: and acquiring the position information of the indoor personnel. Specifically, the position information of the indoor people can be obtained by detecting the positions of the indoor people through a position sensor, detecting the positions of the indoor people through an infrared sensor, and photographing through a camera to obtain the positions of the indoor people. In the embodiment, the position information of indoor personnel is mainly acquired by using the infrared camera.
Step S320: whether or not there is an unmanned area is determined based on the position information of the indoor person and the ranges of the plurality of air supply areas divided in advance. Specifically, fig. 5 shows a schematic diagram of a division manner of an air supply area (an angle of view is a top view angle of the air conditioner), as shown in fig. 5, the air supply range of the vertical swing blade assembly 3 can be divided, a solid line in fig. 5 indicates a first state 31 (i.e., an initial state) of the vertical swing blade assembly, a dotted line indicates a second state 32 (i.e., a state of swinging counterclockwise to a maximum angle) of the vertical swing blade assembly, and a dot-dash line indicates a third state 33 (i.e., a state of swinging clockwise to a maximum angle) of the vertical swing blade assembly. In fig. 5, the air blowing range of the vertical vane assembly 3 is a sector having a central angle θ, and the sector may be equally divided into a plurality of air blowing regions, and in the present embodiment, the central angle θ is 60 ° and equally divided into 3 air blowing regions, and the central angle of each air blowing region is 20 °, each of which includes a left region i, a middle region ii, and a right region iii. If no indoor person exists in the air supply area, the air supply area is an unmanned area. In addition, θ may also be other acute angle values, and is not limited herein.
Step S330: if so, controlling the air outlet direction of the vertical swing blade assembly 3 to point to the unmanned area.
Specifically, the unmanned area here may be one or more. If the number of the unmanned areas is only one, the air outlet direction of the vertical swing blade assembly 3 is directly controlled to point to the unmanned areas, the vertical swing blade assembly 3 can deflect to the central line position of the air supply area to be kept unchanged, and the air can also swing back and forth in the air supply area to sweep air. And if the number of the unmanned areas is multiple, controlling the vertical swing blade assembly 3 to stay in each unmanned area for a second preset time in sequence. Similarly, the vertical swing blade assembly 3 may stay at the center line position of each unmanned area for a second preset time, or may swing back and forth within each unmanned area to sweep wind for the second preset time. The second preset time may be preset by the system, or may be modified manually by the user through voice, a remote controller, or a mobile terminal.
Step S340: if not, the vertical swing blade assembly 3 is controlled to point to each air supply area in sequence.
In particular, it is here meant that no unmanned areas are present, i.e. that there is a person in each of the blowing areas. At the moment, the vertical swing blade assembly 3 is controlled to sweep air in the whole air supply range, and a certain area is prevented from being blown directly.
Step S310 further includes: and acquiring the appearance characteristic information of the indoor personnel.
Specifically, the appearance feature information here may be a face image of an indoor person shot by a camera, or a height value of the indoor person obtained by processing and analyzing the shot image.
Step S340 further includes:
step S341: and determining whether a child-free area exists in the ventilation area based on the appearance characteristic information of the indoor personnel.
Specifically, if the appearance feature information is a face image, determining whether the image contains a face region by recognizing shapes of eyes, a nose, a mouth and the like and geometric relations among the shapes in the image, and determining whether the face in the image is a child face by judging whether an eye distance is smaller than a threshold value or not when the image contains the face region; the collected images can also be input into a pre-trained face recognition model to obtain the recognition result of the child face of the images, wherein the pre-trained face recognition model can be obtained by performing supervised training on the existing convolutional neural network structure by using a machine learning method and a training sample, and the training methods are the prior art and are not repeated herein.
If the appearance characteristic information is a height value, the height of the indoor person in the image can be calculated, for example, comparison calculation can be performed by taking a certain fixed object in the room as a reference object. If the height value is smaller than a preset height threshold value, for example 1.2m, it can be determined that the indoor person is a child. Considering that children belong to vulnerable groups and are more easily affected by the direct blowing of the air, discomfort is caused, so that an air supply area where children exist is a protection area, and the direct blowing of the air is avoided as much as possible.
Step S342: if so, controlling the air outlet direction of the vertical swing blade assembly to point to the zone without children.
In particular, the no-child zone here may also be one or more. Similar processing to that in step S330 is performed, and will not be described here.
Step S343: if not, the vertical swing blade assembly is controlled to point to each air supply area in sequence.
In particular, it is here meant that no zones without children are present, i.e. that there are children in each of the blowing zones. At the moment, the vertical swing blade assembly 3 is controlled to sweep air in the whole air supply range, and a certain area is prevented from being blown directly.
Further, in the embodiment of the present invention, the control method of the air conditioner further includes an air conditioner protection function, which specifically includes:
step S410: and determining whether the indoor personnel are children or not based on the appearance characteristic information of the indoor personnel. Specifically, the determining method refers to step S341, which is not described herein again.
Step S410: if yes, the distance between the child and the air conditioner is measured, and when the distance is smaller than or equal to a preset distance threshold value, the first transverse swinging blade assembly 4 is controlled to be closed.
Specifically, when the distance between children and the air conditioner is less than or equal to the preset distance threshold value, it is too close to the air conditioner to judge that children are close to the air conditioner, and the first horizontal swinging blade component 4 can be closed to prevent children from stretching hands to enter the air conditioner, and the second horizontal swinging blade component 5 and the vertical swinging blade component 3 still normally operate at the moment, so that the use requirements of users are met. Meanwhile, after the first transverse swinging blade assembly 4 is closed in place, a protection program is started, the motor of the first transverse swinging blade assembly 4 is kept to be electrified and rotated continuously in the closing direction, the first transverse swinging blade assembly 4 is limited in the closing in place, so that the first transverse swinging blade assembly 4 is prevented from being excessively rotated, and a certain torque force can be always provided when the motor is continuously electrified, so that children are prevented from easily rotating the first transverse swinging blade assembly 4 and stretching hands into the air conditioner.
Step S410 specifically includes:
step S411: and acquiring an indoor image in real time by using a camera.
Step S412: when the child is located at the boundary of the indoor image, a plurality of indoor images within a third preset time before the current time point are obtained, and a first distance between the child in each indoor image and the air conditioner is calculated.
Specifically, the process of measuring the first distance between the child and the air conditioner may be completed by a ranging program carried by the camera, and the specific ranging principle and method are both in the prior art, for example, the monocular ranging method may refer to a chinese patent "a monocular vision ranging method (publication No. CN 109489620A)", the binocular ranging method may refer to a chinese patent "a binocular ranging system based on STM32 single chip microcomputer and a ranging method thereof (publication No. CN 103913149A)", and the like, which are not described herein again. When the child is located at the image boundary, it needs to be determined whether the motion trend of the child is far away from the air conditioner or close to the air conditioner, and if the motion trend of the child is close to the air conditioner, a potential safety hazard may be generated.
Step S413: and determining whether the child approaches the air conditioner gradually or not based on a plurality of first distances within a third preset time.
Specifically, the judgment of the movement trend here may be obtained by analyzing a first distance between the child and the air conditioner in a plurality of images continuously acquired within a third preset time, and a curve of the first distance versus time may be constructed, where if the first distance gradually decreases with increasing time, it indicates that the child gradually approaches the air conditioner.
Step S414: and if so, measuring a second distance between the child and the air conditioner by using a radar, and controlling the first yaw blade component to be closed when the second distance is smaller than or equal to a preset distance threshold value.
Specifically, when it is determined that the child gradually approaches the air conditioner and disappears from the camera, it is indicated that the child is already at a short distance below the air conditioner, and the radar is started to perform short-distance measurement to obtain a second distance. If the second distance is smaller than or equal to the preset distance threshold, it indicates that a potential safety hazard exists, and at this time, the first yaw blade assembly 4 is controlled to be closed.
